On Dec. 27, 1820, Thomas Jefferson wrote about his vision for the University of Virginia (chartered in 1819), “This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow the truth wherever it may lead, nor to tolerate any error as long as reason is left free to combat it.”

But what should happen 200 years later when our public schools and universities avoid the testing of truths? Or suppress alternate opinions because they are unpopular or politically incorrect? Or no longer tolerate opinions now considered errors or obsolete by the elite? What happens when sociopolitical agendas or scientific paradigms dominate academic views to the exclusion of a minority even being mentioned?

What happens when the political and public educational pendulum swings from concern for the tyranny of sectarianism in Jefferson’s day to secularism in ours? What happens when U.S. public schools become progressive indoctrination camps?

Dr. Jim Nelson Black, founder and senior policy analyst of the Sentinel Research Associates in Washington, D.C., wrote an excellent book, “Freefall of the American University.” In it, he documents the clear biases pervading our public academic settings. Among that lopsidedness is the intentional training of students to disdain America, freely experiment sexually, forcefully defend issues like abortion and homosexuality, as well as become cultural advocates for political correctness, relativism, globalization, green agendas and tolerance for all.

One of the primary ways these educative platforms are spread is by recruiting and retaining faculty members who reflect and teach them. For example, citing from the polling firm of Luntz Research, Dr. Black notes that the 57 percent of faculty members represented in our most esteemed universities are Democrats (only 3 percent Republican) and 64 percent identify themselves as liberal (only 6 percent conservative). Moreover, 71 percent of them disagree that “news coverage of political and social issues reflects a liberal bias in the news media.” And the No. 1 answer they gave to the question, “Who has been the best president in the past 40 years?” was Bill Clinton (only 4 percent said Ronald Reagan).

This is why it is no surprise that the two largest teachers unions, the NEA and AFT, are the largest campaign contributors in the nation (giving more than the Teamsters, NRA or any other organization), and that 90 percent of their contributions fund Democratic candidates. In doing so, do we think such funding is going to balance traditional and conservative values in public schools?

The impact of progressivism is being experienced by students across this land, hundreds of thousands of whom have already cried out with complaints of academic inequity. A sampling of the hundreds of student grievances from across the academic spectrum can even be found on websites like the Students for Academic Freedom and NoIndoctrination.org.

It is also no surprise that an average of 6,000 students every year is leaving the approximately 94,000 public schools in America. If the power-to-be over our public schools, like government and unions, continue to oppose conservative curricula and impose overarching liberal educational revisions and laws, public schools will continue to experience an exodus.

I fully realize there are some great conservative people on the staffs of many public schools and universities, but I know virtually all of them would concur that a liberal bias in our academic curricula and system is overwhelmingly dominant and ubiquitous.

Is this present, restrictive and one-sided educational environment that which Thomas Jefferson and other founders intended for the future generations of America? Absolutely not! Rather than encourage free thinking, the U.S. academic system has turned Jefferson’s plans for open education into our culture’s system of indoctrination.
